The embodiments described below by referring to the drawings are exemplary only, and are used to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0027] The terms "first", "second" in the description and claims of the present application can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0028] Referring to Figure 1 , Figure 1 is a flowchart of a positioning processing method according to an embodiment of the present application, the method is applied to an electronic device, the electronic device includes N antennas, any two adjacent antennas in the N antennas are arranged at intervals, N is an integer greater than 1, as shown in Figure 1 the method includes the following steps:

[0029] Step 101, obtaining a first signal detection parameter, the first signal detection parameter is a parameter detected by each antenna in the N antennas;

[0030] Among them, each antenna in the N antennas can be used to receive a signal, and the first signal detection parameter can be determined according to the received signal.

[0031] The combination of the N antennas can be referred to as an ultra wide band (UWB) antenna combination, and the combination of the N antennas can be a combination of preset arrangement shapes. The specific arrangement shape of the preset arrangement shape is not limited herein. As an optional implementation, the preset arrangement shape can be a rectangle, or, as another optional implementation, the preset arrangement shape can be an L shape. Figure 3 Figure 2

[0032] It should be noted that each of the antennas in the UWB antenna combination can be used to measure a distance, and a plurality of antennas in the UWB antenna combination can be combined and used to measure an angle.

[0033] It should be noted that any two adjacent antennas in the N antennas included in the combination of the preset arrangement shapes are arranged at intervals. As an optional implementation, the N antennas are arranged in an array, so that the receiving effect of each position of the electronic device provided with the N antennas is relatively uniform.

[0034] In step 102, in a case where a first signal detection parameter of a first antenna meets a preset detection condition, a preset calibration parameter corresponding to the first antenna is acquired, the first antenna being any antenna in the N antennas.

[0035] When the first signal detection parameter of the first antenna meets the preset detection condition, it can be determined that the first antenna is blocked or in contact with a conductive body (such as a human body), so that the radiation performance of the first antenna is affected, and the first antenna being blocked can include a scenario in which the first antenna is blocked by an obstacle.

[0036] It should be noted that the specific content of the first signal detection parameter is not limited herein.

[0037] As an optional implementation, the first signal detection parameter includes at least one of a signal strength parameter of each antenna and a received signal phase difference parameter of any two adjacent antennas.

[0038] The signal strength parameter can be referred to as a received signal strength indicator (RSSI), and the received signal phase difference parameter can be referred to as a phase difference of arrival (PDOA).

[0039] In the implementation of the present application, since the first signal detection parameter includes at least one of the signal strength parameter and the received signal phase difference parameter, the diversity and flexibility of the content of the first signal detection parameter are enhanced.

[0040] ​​Meanwhile, when the first signal detection parameter includes the signal strength parameter and the received signal phase difference parameter, the error of the judgment result can be reduced compared with the case where the first signal detection parameter only includes one kind of content, and thus the accuracy of the judgment result when judging whether the first signal detection parameter meets the preset detection condition is higher.

[0041] As an optional implementation, the detection parameter includes a signal strength parameter of each antenna and a received signal phase difference parameter of any two adjacent antennas, and the N antennas further include a second antenna which is arranged apart from the first antenna.

[0042] In the case where the first signal detection parameter of the first antenna meets the preset detection condition, the preset calibration parameter corresponding to the first antenna is acquired, including:

[0043] In the case where the change rate of the received signal phase difference parameter between the first antenna and the second antenna is greater than a first preset threshold and the change rate of the signal strength parameter of the first antenna is greater than a second preset threshold, the preset calibration parameter corresponding to the first antenna is acquired.

[0044] Wherein, the specific values of the first preset threshold and the second preset threshold are not limited herein. The change rate of the received signal phase difference parameter and the change rate of the signal strength parameter of the first antenna can refer to the change rate of the received signal phase difference parameter within a certain period of time and the change rate of the signal strength parameter of the first antenna within a certain period of time. The above certain period of time can be represented by Δt, and the specific length of the above certain period of time is not limited herein.

[0045] Wherein, the received signal phase difference parameter can be a parameter acquired in real time, or the received signal phase difference parameter can also be acquired every preset period.

[0046] It should be noted that the order of the execution steps of the two steps of whether the change rate of the received signal phase difference parameter is greater than the first preset threshold and whether the change rate of the signal strength parameter is greater than the second preset threshold is not limited herein.

[0047] As an optional implementation, the change rate of the received signal phase difference parameter is first determined whether it is greater than the first preset threshold, and then the change rate of the signal strength parameter is determined whether it is greater than the second preset threshold. Since the received signal phase difference parameter is a parameter used to support the UWB function, the received signal phase difference parameter can be obtained in real time. The change rate of the received signal phase difference parameter is first determined whether it is greater than the first preset threshold, and then the change rate of the signal strength parameter is determined whether it is greater than the second preset threshold. This can improve the system operation efficiency, and improve the calculation efficiency and the accuracy of the calculation result.

[0048] In the embodiments of the present application, the preset calibration parameter corresponding to the first antenna is obtained only when the change rate of the received signal phase difference parameter between the first antenna and the second antenna is greater than the first preset threshold, and the change rate of the signal strength parameter of the first antenna is greater than the second preset threshold. In this way, the phenomenon of mistakenly obtaining the preset calibration parameter corresponding to the first antenna can be reduced, thereby saving the calculation resources.

[0049] In step 103, the positioning information of the to-be-detected target is determined according to the preset calibration parameter.

[0050] The specific content of the to-be-detected target is not limited herein. As an optional implementation, the to-be-detected target can be an object located within a preset range of the electronic device. The object can be a human body, a vehicle, or an electronic device, etc.

[0051] It should be noted that the specific manner of determining the positioning information of the to-be-detected target according to the preset calibration parameter is not limited herein. As an optional implementation, the positioning information of the to-be-detected target can be obtained, and then the positioning information is calibrated according to the preset calibration parameter. Alternatively, as another optional implementation, the preset calibration parameter can be run first, and then the positioning information is obtained based on the antenna running the preset calibration parameter.

[0052] As an optional implementation, the method further comprises:

[0053] The second signal detection parameter is determined based on the target signal sent by the first antenna, and the second signal detection parameter is obtained. The second signal detection parameter is a parameter detected by M antennas of the N antennas. The target signal is used to position the to-be-detected target. M is an integer greater than 1 and less than or equal to N.

[0054] In the case where the second signal detection parameter of the first antenna meets the preset detection condition, the third antenna is controlled to send the target signal, and the preset calibration parameter corresponding to the third antenna is obtained. The third antenna is any antenna of the M antennas, and the third antenna is different from the first antenna.

[0055] The second signal detection parameter can refer to the above-mentioned first signal detection parameter, and details are not described herein again.

[0056] In the embodiment, when the second signal detection parameter of the first antenna in the M antennas satisfies the preset detection condition (i.e., it can be considered that the first antenna is blocked or in contact with a conductor, resulting in poor performance), the radiating antenna can be switched from the first antenna to the third antenna, and the preset calibration parameter of the third antenna is obtained, so that the radiation performance of the electronic device can be ensured to be good.

[0057] As an optional embodiment, the electronic device includes a radio frequency transmitter and a control switch, the radio frequency transmitter is connected with each of the N antennas through the control switch, and the radio frequency transmitter is configured to generate the target signal.

[0058] In the case that the second signal detection parameter of the first antenna satisfies the preset detection condition, the third antenna is controlled to transmit the target signal, including:

[0059] In the case that the second signal detection parameter of the first antenna satisfies the preset detection condition, the control switch is controlled to be switched, so that the radio frequency transmitter is switched from the state of being in conduction with the first antenna to the state of being in conduction with the third antenna, and the target signal is transmitted through the third antenna.

[0060] It should be noted that the control switch is switched, which can also be understood as switching the above-mentioned control switch between different states, and the specific type of the control switch is not limited herein, for example: the control switch can be an SP4T (single pole four throw) switch, the input end and different output ends of the control switch can be controlled to be in conduction, so as to realize the conduction of different circuits.

[0061] The second signal detection parameter can refer to the above-mentioned first signal detection parameter, and details are not described herein again. Figure 4 The electronic device can include a UWB integrated circuit (IC), the UWB IC can include a radio frequency transmitter (i.e., TX) and four radio frequency receivers (i.e., RX1, RX2, RX3 and RX4), and the control switch can include a first control switch and a second control switch, so that the switching between the radio frequency transmitter and different antennas (i.e., antennas ANT1, ANT2, ANT3 and ANT4) can be realized through the switching of the first control switch and the second control switch, and the switching between different radio frequency receivers and different antennas can be realized.

[0062] In this embodiment of the application, by controlling the switching of the switch, the switching of the radio frequency transmitter between different antennas can be made more flexible.

[0063] As an optional implementation, obtaining the second signal detection parameters includes:

[0064] When the first antenna group is in operation, the second signal detection parameters are acquired, wherein the first antenna group includes the M antennas;

[0065] The step of controlling the third antenna to transmit the target signal when the second signal detection parameters of the first antenna meet preset detection conditions includes:

[0066] When the second signal detection parameters of the first antenna meet the preset detection conditions, the second antenna group is controlled to be in working state, and the third antenna is controlled to send the target signal. The second antenna group includes the third antenna and the fourth antenna, and the fourth antenna is spaced apart from the third antenna.

[0067] In this embodiment, the N antennas can be divided into different antenna groups. When some antennas in the first antenna group are blocked or come into contact with a conductor, the second antenna group can be switched to the working state, thereby ensuring good radiation performance of the electronic device.

[0068] It should be noted that some antennas in the first antenna group and the second antenna group can overlap, meaning that some antennas can be located in either the first antenna group or the second antenna group.

[0069] As an optional embodiment, see [link to relevant documentation]. Figure 3 The electronic device is equipped with four antennas: ANT1, ANT2, ANT3, and ANT4, which are spaced apart. In the default mode, ANT1 is the transmitting antenna, and ANT1, ANT2, and ANT4 form a UWB antenna combination. When ANT1 is blocked or in contact with a conductor, ANT2, ANT3, and ANT4 are combined to form a UWB antenna combination, and the transmitting antenna switches to ANT3. When ANT2 is blocked or in contact with a conductor, ANT1, ANT3, and ANT4 are combined to form a UWB antenna combination, and the transmitting antenna switches to ANT4. When ANT3 is blocked or in contact with a conductor, ANT1, ANT2, and ANT4 are combined to form a UWB antenna combination, and the transmitting antenna switches to ANT1. When ANT4 is blocked or in contact with a conductor, ANT1, ANT2, and ANT3 are combined to form a UWB antenna combination, and the transmitting antenna switches to ANT2.

[0070] It should be noted that the preset calibration parameters can also be different when different antenna groups are in operation. Optionally, when ANT2 is blocked or in contact with a conductor, ANT1, ANT3, and ANT4 are combined to form a UWB antenna combination, and the transmitting antenna is switched to ANT4. The preset calibration parameters at this time can be obtained by fitting the PDOA data between antennas ANT1 and ANT4, the PDOA data between antennas ANT3 and ANT4, and the Angle-of-Arrival (AOA) information. The aforementioned Angle-of-Arrival information can also be referred to as angular measurement information.

[0071] It should be noted that the preset calibration parameters for each antenna can be pre-measured and stored in the electronic device, and can be directly called up when in use, thus saving calling time and improving calling efficiency.

[0072] As an optional implementation, the method further includes:

[0073] Obtain the angle measurement information of the first antenna, as well as the phase difference parameter of the received signals between the first antenna and the second antenna, and set the interval between the second antenna and the first antenna;

[0074] The preset calibration parameters are obtained by fitting the angle measurement information and the phase difference parameter of the received signal.

[0075] The angle measurement information can be understood as the aforementioned angle of arrival (AOA). Furthermore, there can be a one-to-one correspondence between the angle measurement information and the phase difference parameter of the received signal. Thus, once the phase difference parameter of the received signal is determined, the angle measurement information can be determined.

[0076] In this embodiment, preset calibration parameters are obtained by fitting the angle measurement information and the phase difference parameter of the received signal, thereby making the determination of preset calibration parameters more diverse and flexible.

[0077] In this embodiment of the application, according to steps 101 to 103, when the first signal detection parameter of the first antenna meets the preset detection conditions, it is determined that the first antenna is blocked. At this time, the preset calibration parameter corresponding to the first antenna can be obtained, and the positioning information of the target to be detected can be determined according to the preset calibration parameter, thereby enhancing the accuracy of the positioning information result.
